W W Vs V V

Weight in grams of solute weight in grams of solution g g v v. Therefore to figure out the w v of a 100ml solution that is made up of 65g nitric acid we would divide 65g by 100ml and then multiply the answer by 100. Although there are examples to the contrary it should be stressed that the commonly used units of w v are grams milliliters g ml.
